A minimized architecture for transmitting high-rate data through a small antenna

Abstract

Summary form only given. As the wireless communication devices shrink in size, transmission bandwidth becomes a challenging factor for antenna designers. For example, biomedical implants are among the most critical devices that are required to have a minimized size while transmitting high data-rate information. Particularly, devices that interact with the nervous system such as cochlear and visual prostheses must be able to transmit a large amount of data in order to provide a high-resolution sensing for the user. Even though a high data-rate can be achieved by increasing the carrier frequency in broadband systems, in low-frequency applications high-bandwidth data-transmission remains as a challenging requirement. Furthermore, power consumption and the overall size of the device is a key point in many wireless units such as biomedical implantable devices.
